As you said one is the Great Wall of China.
The other is the Fresh Kill landfill situated on the western shore of Staten Island. Fresh Kill covers 3,000 acres and the highest mound is taller than the Washington Monument. It is also where all the debris from the World Trade Centers was taken.
These are not the only things seen with the naked eye from space, but I was thinking in terms of single construction type things. The lights of Vegas are more cumulative. I guess I should have been more specific.
